centos6.7 和 fedora 23 配置开机启动脚本

最近服务器需要做一些开机启动服务，我的虚拟机是fedora23 的 网上看了下配置如下，试了下 也确实OK

sudo vim /etc/rc.d/rc.local

在/etc/rc.d/rc.local文件中写入, 然后使用:wq命令 保存并退出.

#!/bin/bash

  # 在这个文件中写入开机启动需要执行的命令

赋予可执行权限:

sudo chmod+x /etc/rc.d/rc.local

设置开机启动:

sudo systemctl enable rc-local.service

如果出现以下错误提示:

The unit files have no [Install] section. They are not meant to be enabled

using systemctl.

Possible reasons for having this kind of units are:

1) A unit may be statically enabled by being symlinked from another unit's

  .wants/ or .requires/ directory.

2) A unit's purpose may be to act as a helper for some other unit which has

  a requirement dependency on it.

3) A unit may be started when needed via activation (socket, path, timer,

  D-Bus, udev, scripted systemctl call, ...).

sudo vim /usr/lib/systemd/system/rc-local.service

在rc-local.service文件末尾加入:

[Install]

WantedBy=multi-user.target

并重新设置开机启动:

sudo systemctl enable rc-local.service

重启计算机，完成！

reboot

但是服务器是Centos6.7的，没有systemctl这个命令 网上简单查了下，也没找到设置的方式，后来查到一篇文章

说是只要chmod +x /etc/rc.d/rc.local 即可，

试了下，在re.local里面写了个 echo ccc > ~/a.txt

直接重启机器,果然a.txt 里面内容是ccc 

记录一下，免得忘记。
